How to change desktop icon size?@zarpio This is because you're using the newer "dconf-editor." There's really very little reason to use this anymore for the same issue. There are better GUI fixes available like from the other answers. But if you must, since the editor controls offer more minutiae, the tree in the dconf Editor for nautilus has been moved to "org/gnome/nautilus."

What's the most convenient way to share Steam apps between different users?@SamWatkins Yeah. The folders don't stay ugo+rwx. I've only had problems though when games are updated. The game is locked to the user who initiated the update so that it can't be touched by others until the update finishes on the initial user. Others can't continue the update it while this is going on; it gives a disk write error. I think when the update is done, everything works fine again, since I've only noticed problems when updating. It sucks, unfortunately.

My steam won't start!I had a similar error messages so I tried this out and it worked. I couldn't have thought that it was a graphics diver issue because Steam worked on one user account but not on another. I just installed the open-source driver then started Steam. I didn't have to re-install.
